Hello,

Do the M&P 15-22 magazines, the 10 rnd ones, work in a Mil Spec lower using a CMMG or other 22 conversion? There doesn't seem to be any short magazines to use on a bench rest.

Anyone know the length of the 10 rnd magazine? Is it the same as a GI 20 rnd mag?

Thanks

If you use the Redi Mag adapter

The redi mag adapter is a great option with the benefit of a working bolt hold open device.

Or you could use the mags from Black Dog machine, but no bolt hold open option with these.

AR15.22 15 ROUND MAGS

I use the Redi Mag adapter with MP15-22 mags and it works great!!

That Redi Mag adapter looks incredible!!

Wish someone had a short mag that's about the size of the mag well bottom, a 5 rounder. CMMG was working on one but that disappeared from their site.

From pictures I've seen, looks like the S&W 10 rnd mag is the same size as a GI 20 rnd.

Thanks

I wish I could use the Redi Mag adapter in my Sig522.

Could be possible, the unit is aluminum. it might have to be fitted and tweaked though.

S&W has short 10 round magazines...

Product: M&P15-.22 10 Rd Magazine

Yeah but they won't work in a regular AR without the RediMag adapter. I have always had trouble getting my RediMag adapter to work the way I wanted it to work in my AR-22. So I just use the BDM 15 rd mags instead. They work fine on my benchrest.

Isn't the whole thread about using the 15-22 mags and what it takes to use them? It had already been noted that the RediMag adapter was needed.

My RediMag adapter works great in my rifle. I prefer to have the bolt hold open to mimic the manual of arms of my 5.56 AR.

It'd sure be nice if the other part of my question got answered. How long is the 10rnd S&W Short 15-22 mag or how much of it sticks out below the mag well.

Thanks

Well, did you look at the link I provided? It is obviously shorter than a 20 round GI mag. I can't answer your question on exact length as I don't use those mags... not a bench rest shooter with an AR.

The 10-round short magazine is 4.5 inches long and extends 1.5 inches below the mag well.

I have no idea how long an 20-round AR magazine is, but my Mini-14 magazine is 5.0 inches long.

Yes I did. The pic doesn't show it in relation to anything.

Thanks

That dimension is what I was looking for.

Thanks!!

It is a 10 round magazine... obviously shorter than a 20 round GI magazine.

A simple google search could have answered all of your questions, yet you come here and expect everyone to do your research for you...

WOW!!!!! What's your problem man???? If you don't have something positive to add why bother.

It's NOT """obviously shorter than a 20 rnd GI mag you state 2 times""", as Majorlk pointed out, the S&W 10 rnd mag is 4.5" which is the same as the GI 20 rnd. Maybe you've never seen a 20 rnd GI mag sticking out of an AR. Everything nowadays is 30 rnd. Your research was no good and you're info is wrong.

I already saw your video and it compares a 10 rnd S&W mag to a 30 rnd S&W mag, not a 20 rnd GI mag. I needed the length. Majorlk answered the question, plain and simple with no drama. You didn't. Nobody's asking you to do any work (that is wrong) for anyone except for the length which you didn't provide. Nobody asked you to go out and find a video that doesn't answer the question and post a link and spend your precious time then post a caustic comment.

Your first post was in response to me referring to a mag that was flush with the mag well. Your picture/link wasn't that. Bob Sled has a flush single rnd mag for the mil spec lower using centerfire ammo and CMMG had a flush 22 mag EVO but discontinued it. Someone on this site showed how he cut down a mag to fit flush. Obviously there's a demand for that. NRA Highpower Match rules used to require a flush mag for AR type match rifles. They've changed it in recent years.

Showing a picture of the mag when someone asks 2 times what the length is adds no value. I've seen pictures all over the web and nobody put a length with the pics. S&W even made a medium length 10 rnd mag for a time. I indicated I thought S&W's 10 rnd mag may be the same as a GI 20 rnd mag yet you posted a pic of the mag then asked if I looked at your link. How do you think I thought the 2 were the same length if I didn't already see pics all over the net?

If you get that upset with my comment which wasn't negative at all (even thanked you), just have to wonder what else you get that upset over. Your incorrect posts added no value to this discussion and that upsets you. Maybe if you have nothing positive to add, keep your negative thoughts to yourself. Get a life!!!!!!!!

And to the others that posted positive comments, Thanks!! I appreciate it. Didn't know about the adapter and got the mag length I asked. Majorlk took the time to measure his mags, even put one in and measured the length sticking out and Shawnr5 posted the first link to the adapter. Got what I was looking for.

From your post, it appeared to me that you had not seen the short 10 round magazines, only the long 10 rounders. Had you simply said thanks, those are the ones I am looking at, or talking about, I would have moved on... Your statement of "It'd sure be nice if the other part of my question got answered" came off as sarcastic and uncalled for, thus my response.

Actually, it's not obvious at all; the difference is only 0.5 inch. The 10-round 15-22 magazine is single stack while the 20-round AR (and Mini-14) magazine is double stack.

I'm under no obligation to thank you for anything you posted even though I did. Nothing you posted added anything to the thread. The only Sarcastic and Uncalled For posts were yours which included incorrect info. Guess if someone doesn't thank you for your posts, you make Sarcastic & Uncalled For negative comments. How you could read into any posts in this thread as negative is amazing, then to have you make the comment you did, well what can I say other than "it sure was nice Majorlk answered the other part of my question!!!!"

I wasn't expecting you to thank me... you could have simply stated that the magazine that I posted was the one you were inquiring about... again, from your post, it did not sound as if you knew about the shorter ones vs. the longer 10 rounders that are the same size as the 25 round magazines, and I took your comment to be sarcasm... If I was wrong there, I apologize.

How would anyone take a comment such as "It'd sure be nice if the other part of my question got answered" as anything other than snarky?

You got the answer you were looking for, sorry I couldn't or didn't help you... have a nice day.
